TECHNICAL FIELD

The disclosure relates generally to HVAC controllers.

BACKGROUND

Heating, ventilation, and/or air conditioning (HVAC) systems are oftenused to control the comfort level within a building or other structure.Many HVAC controllers include a controller that activates anddeactivates one or more HVAC components of the HVAC system to affect andcontrol one or more environmental conditions within the building. Theseenvironmental conditions can include, but are not limited to,temperature, humidity, and/or ventilation. In many cases, such HVACcontroller may include, or have access to, one or more sensors, and mayuse parameters provided by the one or more sensors to control the one ormore HVAC components to achieve desired programmed or set environmentalconditions. Because of the increased complexity of such modern HVACcontrollers, programming and/or operating such devices can be considereddifficult and/or confusing, particularly for novice and/or non-technicalusers. Thus, there is a need for HVAC controllers that are moreintuitive and user friendly to program and operate.

FIG. 2 is a front view of an illustrative HVAC controller 20. In somecases, HVAC controller 20 may represent a manifestation of HVACcontroller 10 (FIG. 1), but this is not required. HVAC controller 20includes a display 22 that is disposed within a housing 24. In somecases, display 22 may be a touch screen LCD display. If desired, display22 may be a dot matrix touch screen LCD display. A dot matrix touchscreen LCD display is a touch screen LCD that permits images such asletters, numbers, graphics, and the like to be displayed anywhere on theLCD, rather than being confined to predetermined locations such as isthe case with a fixed segment LCD. Housing 24 may be formed of anysuitable material, such as a polymeric material.

In some cases, HVAC controller 20 may be configured to providesubstantial display and/or programming functionality. FIGS. 3 through 15provide examples of home screens that may be displayed by HVACcontroller 20. In some cases, home screens may include screens that canbe accessed by a top level navigational menu. In some cases, a homescreen may be a screen that is displayed by HVAC controller 20 as adefault display, or when no other data entry is underway. A home screenmay, if desired, display one or more parameters relating toenvironmental conditions such as indoor and/or outdoor temperatureand/or humidity, expected weather conditions, and/or the status of anyequipment that is at least partially controlled by HVAC controller 20.

In FIG. 3, HVAC controller 20 is displaying on display 22 a home screen24 that includes a navigational bar 26 that may be considered asproviding top level navigation. In some cases, if desired, navigationbar 26 may include one or more of a HOME button 28, a FAN button 30, aHEAT/COOL button 32 and/or a MENU button 34. The function of each buttonwithin navigational bar 26 will be demonstrated, in turn. FIG. 3 is anexample of a screen that may be displayed after a user has pushed HOMEbutton 28.

In some cases, home screen 24 may be considered as having two or moreregions. For example, home screen 24 may include a first region 36 and asecond region 38. In some instances, first region 36 may be consideredas displaying or otherwise providing primary information while secondregion 38 may be considered as displaying or otherwise providingsecondary information. In some cases, primary information may beinformation that is considered to be more important, more interestingand/or more useful than secondary information. To illustrate, firstregion 36 may display one or more of a current temperature reading, acurrent indoor humidity, a schedule status, and the like. Second region38 may display one or more of a date and time, an outdoor temperaturereading, an outdoor humidity reading, an equipment status, and the like.

Home screen 24 may also include a third region 40 that may be used fordisplaying and/or adjusting a parameter value such as a parameter thatis displayed within first region 36 of home screen 24. In some cases,for example, third region 40 may include a parameter 42, an up arrow 44and a down arrow 46. The value of parameter 42 may be increased ordecreased using, as necessary, up arrow 44 and/or down arrow 46.

As illustrated, second region 38 may refer to a left-hand section ofhome screen 24, third region 40 may refer to a right-hand section ofhome screen 24 and first region 36 may refer to a center section of homescreen 24 that is between second region 38 and third region 40. In someinstances, however, one or more of first region 36, second region 38and/or third region 40 may instead be aligned vertically above or belowthe other regions within home screen 24, as desired.

In FIG. 4, HVAC controller 20 is displaying on display 22 a home screen48 that is similar in many ways to home screen 24 (FIG. 3). Home screen48, however, includes a third region 50 that may be used to displayand/or adjust two different parameter values. For example, third region50 may, as illustrated, display both a heating temperature set point anda cooling temperature set point, but this is not required. Third region50 may include a first parameter 52, a first up arrow 54 and a firstdown arrow 56. Third region 50 may include a second parameter 58, asecond up arrow 60 and a second down arrow 62. First parameter 52 may beadjusted up or down using first up arrow 54 and/or first down arrow 56,as appropriate. Second parameter 58 may be adjusted up or down usingsecond up arrow 60 and/or second down arrow 62, as desired.

In some instances, pressing up arrow 44 and/or down arrow 46 (FIG. 3)may cause HVAC controller 20 to display on display 22 a home screen 64as shown in FIG. 5. Home screen 64 may, as illustrated, include a holdbar 66 that is displayed along a portion of display 22. Hold bar 66 mayinclude one or more of an adjustable time button 68, a resume schedulebutton 70, a permanent hold button 72 and a done button 74. Theadjustable time button 68 may include an up arrow 76 and a down arrow78. A user may adjust an ending time for a temperature hold by pressingup arrow 76 and/or down arrow 78, as appropriate. If a user changestheir mind, and wishes to instead return to the programmed schedule,they may do so simply by pressing resume schedule button 70. Once theyhave adjusted the ending time as desired, they may press done button 74.

FIG. 6 is similar to FIG. 5, but includes third region 50 as originallydiscussed with respect to FIG. 4. FIG. 6 shows a home screen 80 thatmight be displayed by HVAC controller if a user has pressed or one ormore of first up arrow 54, first down arrow 56, second up arrow 60and/or second down arrow 62 to adjust a temperature set point.

Returning briefly to FIG. 5, if a user presses done button 74, HVACcontroller 20 may display on display 22 a home screen 82, as shown inFIG. 7. Home screen 82 may include first region 36, second region 38 andthird region 40 as discussed with respect to FIG. 3. However, firstregion 36 may include a hold status button 84 that displays an endingtime for the temporary temperature schedule as well as providing theuser with a way to adjust the temporary temperature schedule. If theuser had instead pressed permanent hold button 72 (FIG. 5), HVACcontroller 22 may instead display a permanent hold status button 86 inplace of hold status button 84. In some cases, HVAC controller 20 maypermit a user to set a temporary temperature schedule that lasts longerthan 24 hours and thus HVAC controller 20 may instead display a holdstatus button 88 in place of hold status button 84 or permanent holdstatus button 86.

FIG. 8 is similar to FIG. 7, but includes third region 50 as originallydiscussed with respect to FIG. 4. FIG. 8 shows a home screen 90 thatmight be displayed by HVAC controller if a user has pressed or one ormore of first up arrow 54, first down arrow 56, second up arrow 60and/or second down arrow 62 to adjust a temperature set point.

FIG. 9 shows an illustrative home screen 91 that in some ways is similarto home screen 82 (FIG. 7), but accounts for HVAC controller 20cooperating with a remote control. One such remote control is describedin U.S. Provisional Patent Application No. 60/991,674 filed Nov. 30,2007, entitled “REMOTE CONTROL UNIT FOR HVAC SYSTEM”, which applicationis hereby incorporated by reference herein. In some cases, a remotecontrol may be used to control one or more of a variety of differentfunctions of HVAC controller 20. In some instances, for example, HVACcontroller 20 may be configured to either sense ambient temperature atHVAC controller 20 using an internal thermal sensor and/or to use atemperature reading from a thermal sensor that may be present within theremote control.

Home screen 91 as illustrated shows that HVAC controller 20 is using atemperature reading from the remote control, as indicated by the text“Sensing from remote” displayed within first region 36 of display 22. Anindividual may instead wish to instruct HVAC controller 20 to use theinternal thermal sensor (or a remote sensor located near HVAC controller20 and communicating wirelessly therewith). A Sense from Here button 93provides the individual with the opportunity to instruct HVAC controller20 to use its internal thermal sensor. In some cases, if HVAC controller20 is using its own thermal sensor, home screen 91 may include a “Sensefrom Remote” button (not illustrated) and/or the remote control mayinclude a button that permits the homeowner to instead sense thetemperature from the remote. A Vacation button 95, as will be discussedfurther with respect to subsequent Figures, permits a homeowner to viewand/or modify temporary vacation-related scheduling.

In some instances, HVAC controller 20 may display a first image withinfirst region 36 of display 22 and a second image within second region38. The first image may include a first set of information while thesecond image may include a second set of information. A third image thatmay include information pertaining to one or more HVAC system statusconditions may temporarily replace the second image otherwise displayedwithin second region 38. In some instances, the first image, the secondimage and the third image may all be displayed on a home screen. In somecases, displaying the third image in place of the second image may notimpact the display of the first image.

In some cases, the first set of information displayed within firstregion 36 may include current indoor temperature, a temperature setpoint, an indoor humidity reading and schedule information. The secondinformation displayed within second region 38 may, for example, includeone or more of date, a time, an equipment status and an outdoor weatherparameter. HVAC controller 20 may, for example, replace the second imagewith the third image when HVAC controller 30 detects the occurrence ofone or more system status events or conditions.

In some instances, HVAC controller 20 may provide messages such asinformational messages, equipment status messages, and the like upon atleast part of display 22, particularly if home button 28 has beenpressed or otherwise chosen or is automatically displayed after, forexample, no user interaction is sensed for a period of time (e.g. thirtyseconds). FIG. 10 provides an illustrative home screen 92 that includesan information button 94. As illustrated, information button 94 may bedisplayed within second region 38 and as such does not interfere orotherwise eliminate any information displayed within first region 36.

Home screen 92 includes third region 40 as discussed with respect toFIGS. 3, 5 and 7.

FIG. 11 provides a home screen 96 that includes information button 94displayed within second region 38, but includes third region 50 asdiscussed previously with respect to FIGS. 4, 6 and 8. In either case,pressing information button 94 may cause HVAC controller 20 to displayfurther information pertaining to the shorter message displayed withininformation button 94.

Information button 94 may provide a variety of equipment statusmessages. An example includes “Your air filter needs to be replaced.”Other examples may pertain to humidifier pad replacement, UV lightreplacement, and other furnace and/or A/C service schedules asappropriate, depending on installed equipment options. FIGS. 10 and 11show information button 94 displaying the aforementioned messageregarding air filter replacement. In some cases, pressing informationbutton 94 (either in FIG. 10 or FIG. 11) will cause HVAC controller 20to display a screen 100, as shown in FIG. 12.

In FIG. 12, screen 100 includes further information pertaining to theequipment status message included on information button 94. Screen 100includes text 102 that provides the homeowner with information regardingwhat needs to be done and/or how to do it. As illustrated, text 102 says“Your system's (equipment name) (e.g. air filter) needs to be replaced.When you have replaced it, please press Reset.” HVAC controller 20 mayfill in the appropriate equipment name, and sometimes provide theappropriate model number and/or appropriate information. The appropriateequipment name, model number and/or other information may reference acurrent value of a variable that is embedded within the informationmessage, if desired.

Screen 100 includes a Reset button 104, which may be pressed once theappropriate equipment has in fact been replaced. In some cases, homescreen 100 may include a Reminder button 106 that provides the homeownerwith a period of time sufficient to address the particular issue. Forexample, Reminder button 106 may temporarily satisfy HVAC controller 20for a period of time long enough for the homeowner to go to the storeand buy the appropriate replacement item such as a new air filter, a newhumidifier pad, or the like.

In some cases, home screen 100 may also include a Dealer button 108.When HVAC controller 20 is initially installed, the installer may, ifdesired and as will be discussed with respect to subsequent Figures,enter information identifying the HVAC contractor. By pressing Dealerbutton 108, the homeowner may, for example, be provided with a telephonenumber or email address for the HVAC contractor and thus the homeownermay simply call the HVAC contractor either to order the appropriatereplacement item and/or to request that the contractor resolve the issueby obtaining and installing the appropriate replacement item.

In some cases, a “Service Request” button may be provided that sends amessage to the identified contractor and requests the contractor toaddress the issue. HVAC controller 20 may contact the contractor byemail message, text message, or the like. The message may, for example,include appropriate part numbers or other diagnostic information so thatthe contractor can bring the appropriate parts and/or equipment. Ofcourse, HVAC controller 20 would have to be provided with telephone orother Internet access in order to provide this functionality.

In some cases, HVAC controller 20 may have more than one message todisplay. In these instances, information button 94 may instead display amessage such as “There are multiple messages.” or something to thateffect. In some cases, screen 100 may include a scroll bar 110 or thelike that provides information pertaining to how many messages arewaiting as well as providing scroll buttons 112 and 114 so that thehomeowner or HVAC contractor may scroll through the messages. If thereis only one message to display, scroll bar 110 may not be displayed.

In some instances, and as illustrated with respect to subsequentFigures, HVAC controller 20 may display a help button that, if pressed,may cause HVAC controller 20 to display one or more context sensitivehelp screens that may provide the user with information that ispertinent to one or more displayed operating parameters. In some cases,the help screen may temporarily replace whatever information was beingdisplayed. The help screens, if displayed, may include informationpertaining to, for example, operating parameters such as circulating fanoperation, system operation, scheduling, humidification and/ordehumidification settings, ventilation settings, maintenance reminders,equipment settings, and the like. In some cases, the help screen mayinclude current values of one or more variables embedded within the helpscreen message, if desired.

In some ways, selecting an indoor humidification setting issimilar to selecting a window frost protection setting, as the risk ofwindow condensation, particularly in cold weather, is at least partiallya function of the indoor air humidity. However, window condensation isalso at least partially a function of the efficiency of the windowswithin the house or other building.

An old, inefficient window such as a single-pane window may present arelatively cold glass surface to the heated atmosphere within thebuilding. Condensation is more likely in this situation. In contrast, anewer, more efficient window such as a double-pane window or even atriple-pane window will present a relatively warmer glass surface to theheated atmosphere within the building. Thus, an efficient window maytolerate a relatively higher indoor humidity without excessive windowcondensation. It will be recognized, of course, that outdoor temperaturemay also play a part. In some cases, HVAC controller 20 may be incommunication with an exterior temperature sensor and may be programmedto adjust humidity settings and/or window frost protection settingsaccordingly.
